Fig. l is a 'section taken at right angles 'to Fig. 2. Fig. 5 is a detail showing ythe position of the lock for the operating rod when the tank is full. l Referring to Fig. 1, "5 and 6 indicate re spectively, bowl which areconnected by the usual ann gularshaped flush pipe 7, the upright side of which forms a contracted continuation of one leg `8 of a siphonawhich is located within the tank 5` and whose other leg 9 is of reater volume than the enlarged portion of the leg 8. The vaction ofthe siphon a is controlled by a siphon b, one of whose legs communicates with and is of greater volume than the leg 9 and'whose other leg 1 1 is of greater volume than the leg 10 and is in direct communication with-'the tank 5.

The action of the siphon b is controlled byv an air cushion in anair chamber i'n the crown lof the salidsiphon, andthe air cushion is confined by a water seal c centaine in a series of concentric' communicating chambers12, the outermost of which coinmunicates.with the atmosphere ,and the iint e thev crown ofthe siphonb 4air chamber in said through a tubular extension 37 of The air cushion is a bell y crank leverlii, one arm of which is .provided with an. adjustable weight 14 which serves to depressashoe the other arm ofthe lever into` contact Specification.

I which forms thel upper "base for the cushion andthe side of the passages betweenthe upper ends of tral chambers A12. crank leverv in one by a push rod 17 mounted in a-bearing 18 in the front side of the 'tank 5 and arranged The y'action of the bell so' as to be convenient for pushing, on the partv of the operator, whenever desired, the

inner end of this rod contacting with an arm 19 on the bell crank lever 13.

The push-rod 17 is `controlled by` alock which /is operated by the rise andfali'- of the water celumnwin' the tank rThis lock includes a `pin or -stud 20 andV a rotatable* y sleeve 21 mounted on the bearing 18 and f provided with a bayonet 'slot 22. 'l'.he turning ofthe sleeve is effected by a float 23 connected tothe sleeve by an arm 2d and the parts are arranged so that "when a predetermined amount of liquid is entered inthe tank, the long'side of the bayonet be in alinementy with the stud 20. so to provide a passage for thestud when the red is pushed inwardly. But when leL `4 than vthe aforesaid predetermined`v .f of

water is inthetank 5, the float whicl follows the surface of the water, is at a ef i ent angle to thevertical than wh side of the slot is in alinement wi.L a e stud the intermediate and cenf ec 'direct-ion, is controlledslot, will Sti 2O with the' result that the sleeve 2l is turned i soas to admit of'the short side' of the slot 2 2 receiving the stud 20 when the push -i'od' isrestored to itsl normal position under' the action of the` bell crank 13.

The supply pipefor any required which extends downwardly into theI andis connected to. the supply pipe by valvev coupling 27, is controlled bv the inlet 25 is directed upwardly' distance through the' bot- 'i .tom of the tank and communication between the .said supply pipe and the inlet pipe 25 f tank' or float controlled valve 28. rlhe iloat 29 for 4the valve 28 isY connected to the said valve dV bv a rod 30 and is contained in a receptacle 31 arranged for a limited amount of bodiiy` movement in a hanger 32 connected to tank Vby brackets 'l-BL figlie passage through'the'receptacle 31 .is controlled by float check valve 34 arrangedin cage depending from the bottoni of the recepta ,e and operating in a valve seat in the bottom of the receptacle. seal cis conducted by a pipe 3G extending from the valve 28 through the inletpipe 26 and upwardly through the central tube 37 The supply for the'water' and into the central chamber, as shown in F1g.,2.

When bringing the device into use with4 'the parts arranged as shown in Figs. 2 and 4, the push rod 17 is forced inwardly so as to rock the bell crank 13 upwardly. The com! pressed air in the Siphon b and central tube 37 now effects the lifting of the bell 16 with the parts connected thereto, and this upward movement on the part ofthe bell increases the ,volume of the air chamber and effects a reduction of air pressure therein.

' Upon obtaining this reduction of pressureandthe chambers 12 discharge into the tube 37. The siphonic action continues until the level of th-e column in the tank is below the edges of the legs 9 and 1l.` Owing to the difference inl volume in the several legs it will be manifest that the supply to the leg -ff of less volume will be at a greater rate'than the discharging of that leg with the result that themaximum rate of discharge through the legs of lesser volume, and especially throughthe contracted portion of the leg 8, will be obtained as long as the siphonic action continues. When the liquid column in the tank 5 is below the inlet end of the leg 11 of the siphon o, the siphonic action will have discontinued. N ow with the inlet valve QS open the water rising above the lower ends of the legs 10 and 11 will coni'ine the air in the siphon b and eii'ect the compression 'of suchair as the said column rises to its normal height. Thus when the water rises above the lower edges of the legs 9 and 10 as previously stated, and to its normal level as shown in Fig. 1, a new air cushion will be provided in the crown of the siphon Z) and tube 37. When the water column in the tank 5 sinks below the lower end of the receptacle 31 the check valve 34 will open the passage for the water to pass from the receptacle 31 into the tank 5. Duringthe lilling of the tank and when the lwater rises into contact with the valve '34, such valve will iioat and seal the passage in the lower end of the receptacle. During this action on the Ypart of the water and prior to its rising to normal level, the float 29 will be arranged wholly within the receptacle, as shown by full lines in Fig.' 2, and thus maintain the valve 28 in the open position. But when the water column approaches its normal height, the

receptacleA 31 which is now immersed in the iuid and 'buoyed into contact with vthe in-A turned upper edge 38 of the hanger 32, will descend under the weight of the water flowv that 'a quick closing action on the part of the i valve 3 8 will be obtained andthe usual hissing no ise prevented. 4'lVhile the water is rising 1n the tank 5 the supply of water to the seal c willalso be had through the pipe 36 and as this supply through the pipe 36 overflows the central chamber, the water will pass into the leg 10 Ao1: the siphon I) and operate to dislodge a suiicient quantity of water from the legt) into the leg 8 and into the goose-neck of the bowl so as to renew the water seal in the said. goose-neck after the flushing of the bowl.

That is claimed as new is:

' 1. ln a flushing apparatus, the combination with a tank; of a push rod arranged in one wall of the tank, a lock for the pushy rod including a pin, a rotatable sleeve having a bayonet slot for receiving the pin, and a float for turning the sleeve.
